In recent times, copula families have been mostly employed in bivariate drought duration and severity. Archimedean copulas are mainly used conveniently among various potential for hydrologic design water resource management. this study, events defined by standard precipitation index (SPI3 time series) series 24-gauge stations Ceyhan Basin Turkey considering different elevation levels (high, ave...

Xinjiang grasslands play a crucial role in regulating the regional carbon cycle and maintaining ecosystem stability, grassland net primary productivity (NPP) is highly vulnerable to drought. Drought events are frequent due impact of global warming. However, there lack more systematic research results on how NPP responds drought its heterogeneity characterized. In this study, CASA (Carnegie Ames...

There are two types of drought as conceptual drought and operational drought. The three parameters as the beginning, the end and the degree of severity of the drought can be identifying in operational drought by average precipitation in the whole region. One of the methods classified to measure drought is Reconnaissance Drought Index (RDI). Evapotranspiration is calculated using Penman-Monteith...

Drought stress restricts the growth of okra (Abelmoschus esculentus L.) by disrupting its biochemical and physiological functions. The current study was conducted to evaluate role selenium (0, 1, 2, 3 mg Se L−1 as a foliar application) in improving tolerance drought (control (100% field capacity-FC), mild (70% FC), severe (35% FC)) imposed 30 days after sowing (DAS). (severe) markedly decreased...

Ecological fingerprints of climate change are becoming increasingly evident at broad geographical scales as measured by species range shifts and changes in phenology. However, finer-scale species-level responses to environmental fluctuations may also provide an important bellwether of impending future community responses. Here we examined changes in abundance of butterfly species along a hydrol...
